Hesperetin is a bioflavonoid and, to be more specific, a flavanone.
Glycosides
A variety of glycosides of hesperetin are known, including:
- Hesperidin (hesperetin 7-rutinoside) is a water-insoluble flavonoid glycoside whose solubility is below 5 μg/ml in water.[1] Hesperidin is found in citrus fruits and upon ingestion it releases its aglycone, hesperetin.
- Neohesperidin is the 7-neohesperidoside of hesperetin.
- Hesperetin 7-rhamnoside can be isolated from Cordia obliqua.[2]
Metabolism
Hesperidin 6-O-α-L-rhamnosyl-β-D-glucosidase is an enzyme that uses hesperidin and H2O to produce hesperetin and rutinose. It is found in the hyphomycetes species Stilbella fimetaria.
